Free TSV ↔ CSV Converter
Switch between tab and comma delimiters effortlessly
Convert Tab-Separated Values (TSV) to Comma-Separated Values (CSV) and back with ease. Perfect for data portability between different spreadsheet applications and database tools. Fully client-side processing ensures your data remains private.
📋 TSV vs CSV Formats
TSV uses tab characters to separate values, making it ideal for data containing commas. CSV uses commas as delimiters and is the most widely supported format. Both are plain text formats for tabular data, but each has specific use cases where it excels.

❓ Frequently Asked Questions
When should I use TSV instead of CSV?
Use TSV when your data contains many commas (like addresses or descriptions) to avoid delimiter conflicts. TSV is also preferred in scientific computing and bioinformatics.
How are tabs represented in the input?
When pasting TSV data, actual tab characters from your source will be preserved. The tool uses PapaParse to correctly identify and convert tab delimiters.
What if my data has both tabs and commas?
The tool treats the selected delimiter as the field separator. If converting TSV to CSV, tabs become field delimiters and commas within fields are preserved as regular characters.
Are line breaks within fields supported?
Yes! The converter properly handles multi-line field values that are enclosed in quotes, maintaining data structure during conversion.
Is my spreadsheet data safe?
Yes! All conversions are performed locally in your browser using the PapaParse library. Your spreadsheet data never leaves your device or gets uploaded anywhere.
